Viewing Comprehensive Monitoring Data
By applying the list and get subcommands against the tree structure using dotted
names, you can display more comprehensive monitoring data, such as a description of
each of the statistics and its unit of measurement.
The following topics are addressed here:
Guidelines for Using the list and get Subcommands for Monitoring
The underlying assumptions for using the list and get subcommands with dotted
names are:
-
A list subcommand that specifies a dotted name that is not followed by a wildcard (*) lists the current node’s immediate children. For example, the following subcommand lists all immediate children belonging to the server node:
list --monitor server
-
A list subcommand that specifies a dotted name followed by a wildcard of the form .* lists a hierarchical tree of child nodes from the specified node. For example, the following subcommand lists all children of the applications node, their subsequent child nodes, and so on:
list --monitor server.applications.*
-
A list subcommand that specifies a dotted name preceded or followed by a wildcard of the form *dottedname or dotted * name or dottedname * lists all nodes and their children that match the regular expression created by the specified matching pattern.
-
A get subcommand followed by a .* or a * gets the set of attributes and their values that belong to the node specified.
For example, the following table explains the output of the list and
get subcommands used with the dotted name for the resources node.
Example Resources Level Dotted Names
|
|
|
|---|
list --monitor |
server.resources |
List
of pool names. |
list --monitor |
server.resources.connection-pool1 |
No attributes, but a message saying “Use get subcommand with the
--monitor option to view this node’s attributes and values.” |
get --monitor |
server.resources.connection-pool1.* |
List of attributes and values
corresponding to connection pool attributes. |
|
For detailed information on dotted names, see the 
dotted-names(5ASC) help page.
To View Comprehensive Monitoring Data
Although the monitor subcommand is useful in many situations, it does not offer
the complete list of all monitorable objects. To work with comprehensive data for
an object type, use the list --monitor and the get --monitor subcommands followed by
the dotted name of a monitorable object.
Before You Begin
A monitorable object must be configured for monitoring before you can display information
about the object. See To Enable Monitoring if needed.
List the objects that are enabled for monitoring by using the list(1)
subcommand.
For example, the following subcommand lists all components and services that have monitoring
enabled for instance server.
asadmin> list --monitor "*"
server.web
server.connector-service
server.orb
server.jms-serviceserver.jvm
server.applications
server.http-service
server.thread-pools
Get data for a monitored component or service by using the get(1)
subcommand.

on instance server.
